The Human Genome Project and its offspring, testing for genetic anomalies, have the prospect in the short-term at least of reducing human welfare. Alex is right that we are largely behind a veil of ignorance with respect to our genetic predispositions to diseases that have not yet presented themselves. Genetic testing removes that veil. No insurance market against genetic disease could survive the asymmetry of information between the insured and the insurer. I have written about this in The Human Genome Project and the Economics of Insurance: How Increased Knowledge May Decrease Human Welfare, and What Not To Do About It, 7 Annual Review of Law and Ethics 219 (1999).
